If 1. Rd4 then 1...Rxf2+ either checkmates or at least wins a bishop for black. If after 1...Rxf2+ 2. Kxf2 then 2...Re2+ 3. Kg1 Qe3+ 4. Kh1 Qxf3+ 5. Kg1 Qg2#. If after 1...Rxf2+ 2. Kg1 then at the very least 2...Rf1+ 3. Qxf1 Qxd4+ wins a bishop for black. Please feel free to correct me if I miscalculated or improve or expand on the second line.

Excellent analysis Bryan!! Here is a picture for those that didn't follow.

What I would add is that after 1...Rxf2 2. Kg1

then 2..Rg2+ 3. Kh1 Qxf3 follows, with threats of discovered check (Rxg3+ followed by Qg2# come to mind) and also Ree2 still, should reinforcements be needed. If White's queen ever leaves the back rank, then Re1# is easy. White can get in a few courtesy checks on Black's King, but White will soon fall.

Thank you. I saw 1. Rd4 Rxf2+ 2. Kg1 Rg2+ 3. Kh1 Qxf3 and suspected it was crushing for black but did not feel like analyzing the courtesy checks to see that there was indeed no perpetual check or even a checkmate for white.

Also any effort by white to challenge the black queen also fails, mainly due to the threat of double check. For example 4. Rf4 allows 4...Rh2+ (double check) 5. Kxh2 Re2+ 6. Kg1 Qg2#.

You should implement a slashdot style moderation system for posts, or at least edit them so that there is actually some chess related material in the thread. I am getting sick of seeing indians writing 'first!'.
